Locating the nanoReel Sonde
The nanoReel is equipped with a Sonde, built into the
camera head, which transmits a locatable 512 Hz signal,
allowing you to detect the camera’s location underground.
Controlling the Sonde from a SeeSnake CCU is
described in the operator’s manual for the CCU and
depends on the model being used. Typically, the Sonde
can be turned ON and OFF from the CCU. If using the
nanoReel with the micro CA-300, activate the Sonde by
turning the LED brightness control down to zero. Once
the Sonde has been located, the LEDs can be returned
to normal brightness to continue the inspection.
When the nanoReel Sonde is turned ON, a locator such
as the RIDGID-SeekTech SR-20, RIDGID-SeekTech
SR-60, Scout, or NaviTrack
®
II set to 512 Hz can detect it.
To locate the camera using the Sonde, run the SeeSnake
push cable from 5 ft to 10 ft [1.5 m to 3 m] into the pipe
and use the locator to find the Sonde’s position. If desired,
extend the SeeSnake push cable from 5 ft to 10 ft [1.5 m
to 3 m] further down-pipe and locate the Sonde again
starting from the previous located position. To locate the
Sonde, turn the locator ON and set it to Sonde mode.
Scan in the direction of the Sonde’s probable location
until the locator detects the Sonde.
Once you have detected the Sonde, use the locator
indications to zero in on its location precisely. For
detailed instructions on Sonde locating, consult the
operator’s manual for the locator model you are using.

Retrieving the Camera
After completing the inspection, pull the push cable back
with slow, steady force. If possible, continue running
water down the line to help clean the push cable. Use a
towel to wipe off the push cable as it is withdrawn.
Pay attention to the force required to withdraw the push
cable. The push cable may get hung up while being
retrieved and may need to be manipulated as done
during insertion. Do not force the push cable or exert
excessive force to avoid damaging the camera or push
cable. When pulling the push cable, keep clear of any
sharp edges and do not pull at sharp angles to the inlet
to prevent damage to the push cable.
NOTICE
Always use short strokes to feed back small
lengths of the push cable back into the drum. Pushing back
longer lengths of push cable or forcing the push cable may
cause it to loop, kink and break (See Figure 21). Lay the
nanoReel drum on its back for more stability when retriev-
ing the push cable.

Using Guide Tubes
Use guide tubes, such as PVC or flexible tubing, to avoid
marring or scratching porcelain surfaces (
See Figure 22).
Figure 22 – Guide Tubes
Use PVC pipe and conduit to form a guide tube with a
curved access tube at the bottom to guide the push cable
past the porcelain without damage (
See Figure 23).
